Given numbers are 421,674,199,454

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 421,674,199,454 is 12818019442.

Find LCM of 421,674,199,454 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 421 x 337 x 199 x 227 = 12818019442

Therefore, the lowest common multiple of 421,674,199,454 is 12818019442.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

421 x 674 x 199 x 454 = 25636038884

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

421 : 1, 421

674 : 1, 2, 337, 674

199 : 1, 199

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,674,199,454, is 1.

Now, the common factors can be found like this.

421:421

674:2x 337

199:199

454:2x 227

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 25636038884/(1x2)

LCM = 25636038884/2

LCM = 12818019442

Thus, we can understand that the LCM of 421,674,199,454 is 12818019442.
